Miniature rose plant named ‘Poulty026’

ABSTRACT

A new garden rose plant of the Miniature class which has abundant, red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrida.

Variety denomination: ‘Poulty026’.

This application claims priority to Plant Breeder's Rights ApplicationNumber 2020/2273, which was filed at the Community Plant Variety RightsOffice in the European Union on Sep. 21, 2020, the contents of which arehereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of roseplant which originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent, also anunnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2013 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulty026’, originated as a single seedling fromthe stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by the following characteristics. The malepollen parent plant has a growth height of about 35 cm while the newvariety has a growth height of 29 cm. The female seed parent plant has avery dark red flower colour while the new variety has red flowers.

The objective of the hybridization of this rose variety was to create anew and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant red flowers;    -   2. Vigorous, but very compact growth when propagated on its own        roots;    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulty026’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2013 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulty026’ was selected in thespring of 2014 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulty026’ by rooted cuttings was first done byMogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2014.This initial and other subsequent asexual propagations conducted incontrolled environments have demonstrated that the characteristics of‘Poulty026’ are true to type and are transmitted from one generation tothe next.

DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and sterns, of‘Poulty026’.

Specifically illustrated in FIG. 1 of the drawings are open flowers fromabove and the side, flower petals detached, sepals detached revealingreproductive flower parts and receptacle.

Specifically illustrated in FIG. 2 of the drawings are a floweringbranch and mature and juvenile leaves. Plants shown are 4 months in age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulty026’,as observed in its growthin a greenhouse in Odense Denmark. Plants were grown in 24 cm containersunder natural light conditions for a period of 6 months.

For a comparison, several physical characteristics of the rose variety‘Poulpar029’, U.S. Plant Pat. No. 16,148 are compared to ‘Poulty026’.‘Poulpar029’has 30 flower petals, while ‘Poulty026’ has 185 flowerpetals. The general tonality of flower colour for ‘Poulty026’ is Red46B, while the comparison variety ‘Poulpar029’ has a tonality of Red53A. The flower diameter of the applicant variety ‘Poulty026’ is 47 mm,while the comparison ‘Poulpar029’ has a flower diameter of 35 mm.
